Wall Build-Ups

EWI Pro systems are built to last, offering a range of external wall solutions for improving thermal comfort and external appearance. The following are some typical external wall insulation systems using EWI Pro materials. As demonstrated, our systems are highly versatile and can be used to create numerous external wall insulation systems for a range of properties and substrates.

Surface Preparation

The substrate must be clean, dry and dust free. Render carrier board joint tape must be used to secure all joints.

Basecoat

The basecoat reinforcement layer consists of the EWI-225 Premium Basecoat applied directly to the substrate. The basecoat is used to create a smooth surface before rendering.

Fibreglass Mesh

Fibreglass reinforcing mesh is embedded within the basecoat adhesive to enhance the tensile strength and crack resistance of the render system.

Render Primer

The render primer is painted onto the reinforcement layer to ensure that the render adheres to the basecoat, and to contribute towards a durable render finish.

Decorative Finish

EWI Pro offer a range of coloured renders, all of which can enhance the external appearance of the property. Each render provides a long-lasting, crack-proof finish and come with a range of advantages for the building structure.

Ventilated Systems Timber Construction - Render Only

EWI Pro render systems work well on ventilated timber construction buildings as they allow water vapour to pass through the substrate, escaping the external walls and preventing build-up of water vapour. The system allows for the ventilated cavity to remain dry, while also protecting against water ingress.
